4 Claims. 1

This invention relates to a weather sealing means for jalousie windows or, that type of windows generally embodying a plurality of overlapping horizontally disposed swinging panels.

Since the swinging panels of the conventional jalousie windows are normally supported in metallic end clips, with the clips pivotally supported usually, within a rigid extruded aluminum frame, it has been found extremely difficult to successfully exclude Water and air from blowing between the frame and the end clips, since the end clips must of necessity have sufficient freedom of pivotal motion to facilitate the opening and closing of the window. Many attempts have been made to install various forms of weather stripping, none of which have been fully satisfactory and, where the weather stripping has been positioned for contacting engagement by the end clips, it has been found that the continual shifting of the end clips soon destroys the weather stripping, as it will be apparent that the end clips will impart a shearing action upon the weather stripping at each operation of the window.

It is therefore the purpose of this invention to provide a novel form of weather stripping that is supported in a novel manner upon the extruded frame of the window to be partially compressed at all times by the end clips of the jalousie panels and with the novel weather stripping and adjacent area of the frame so constructed that there will be no tendency toward a shearing action but, upon the contrary the end clips will impart a rolling action to the weather stripping Without danger of cutting or otherwise destroying the effectiveness of the weather stripping beyond the normal wear that might be imparted thereto over along period of time.

The invention further contemplates a novel form of weather stripping across the header of the window for contacting engagement by the uppermost panel of the jalousie group when the panel is swung to fully closed position.

Novel features of construction, operation, and arrangement of parts will be more readily understood by referring to the following description taken in connection with the accompanying drawings wherein, like characters of reference are employed to denote like parts throughout the several figures.

In the drawings:

Figure 1 is a substantially central vertical sectional view of a jalousie Window embodying the invention,

Figure 2 is a horizont-al section taken substantially on line 2--2 of Figure 1.

Figure 3 is a fragmentary enlarged horizontal section illustrating the action of the novel weather stripping as the jalousie panel is swung to a closing position,

Figure 4 is a fragmentary perspective view of a section of weather stripping embodying the invention.

Referring specifically to the drawings, the numeral 5 designates a rigid and preferably extruded frame as a whole, embodying side jambs 5, sill 1, and 1a header 8. The particular configuration of the frame is not critical. to this particular invention other than to provide flat surfaces 9 upon the side jambs 6 that extend for the full height of the jambs and which serve as `an additional surface for end clips Il! that swingably support the glass panels. The end clips are pivotally supported upon the surfaces 9 as at l2 and common operating bars I3 serve to simultaneously shift the several end clips and their respective panels II through the medium of conventional links and geared operators I4 and I5, It is to be understood that the end clips, panels Il and associated operating means I3, i4 and I5 form no part of the present invention. The header 8 is provided with a forwardly extending drip shield I6 for substantially its entire length. The drip shield IE is provided with a vertically arranged lip Il that is provided with an inwardly dove-tailed groove I8.

Fixedly positioned within the groove i8 is a flexible weather strip I9 having a dovetailed edge 20 for seating engagement within the groove I8. The weather strip I9 may be formed of rubber, plastic or any other suitable material and serves to effectively seal the upper edges of the uppermost panel against the entry of foreign matter when the jalousie is in a fully closed position.

The forward free edge of the sill 1 is Provided with an outwardly open dovetailed groove 2| that extends for substantially the full length of the sill. Fixedly positioned within the groove 2| is a flexible and deformable weather strip indicated as a whole at 22. The weather strip 22 embodies a solid dovetailed section 23 and an integral forwardly projecting tubular and deformable body portion 24. The section 23 has seating engagement within the groove 2| While the body portion 24 extends forwardly to lie in the path of closing movement of the lower edge of the lowermost panel and its associated end clips. The weather strip 22 may be formed of rubber, plastic or other desirable material.

Each of the jambs 6 for their full height and in substantial vertical alignment with the several end clips when they are in the fully closed position, is provided with dovetail grooves 25 that are inwardly opening and have their edges rounded, as at 2li. From the rounded edges 26, the groove Z5 is flared outwardly, as at 2l. The groove 2t iixedly supports the dovetail 23 of the weatherstrip 22, with the tubular body portion 2B projecting forwardly beyond the surf-ace 9 to be centrally disposed with respect to the .flared groove 2T. The flared groove 21 thus pr-ovides a relatively wide recess for the full height of the jamb sections which recess provides a means that permits of the rolling or deform'ing of the body' portion 2li of the weather stripping 22 when it is frictionally engaged by the end .clips il@ r.during the opening and closing of the window in a man- I ner that will be presently described. The groove therefore oiiers no sharp angles or edges that would shear, cut or injure the body portion 2t Aduring the pivoting of the panel end clips.

VIf found desirable vthe linner circumference of the frame bwhich mcludesthejamb 5,-sil-l land head-er d, may be grooved as at 28 for the Areception of a continuous section of weather stripping E2 which `serves `as 'both a cushion for an insect screen 290i' which will efectually serve to seal the circumferential edge of the screen Yagainst `the entry of insects in lsuch cases where the frame 2S has an improper seat. The weatherstripping 22 4as positioned within the grooves 218, is further very effective as la weather Aseal in cold climates where a storm window is substituted in place of the insect screen 29 thus, in combination with the `weatherstripping around the outer side of the window, providing double protection in cold weather. Asis clearly shown in the drawings and especially in Figure l, the weatherstripping Z2 as supported with the jamb sections ll is substantially in alignment and is effectively engaged by all of thepanel clips Asimultaneously when the window is in fully closed position 'thus `providing a continuousk anduninterrupted seal between the jambs and the clips l0. 'This seal permits of the pivotal mounting of 'the clips I0 with adequate clearance with the ljambs, land yavoids the usual objectionable frictional contact ofthe clips with the jambs, which friotional contact has always 'tended to retard the free operation of the window.

In the use of the invention 'the frame 5 has been extruded and assembled in the usual manner with the weatherstripping t9 and 2'2 installed within `their vrespective grooves. The several end clips are then pivotally,installedupon the surfaces S in overlying relationship tothe weatherstripping '22. The -window having been installed yn the usual manner, the glassv panels vI I are inserted and secured in position Yagainst accidental displacement and the operating means |`3, It and l5 connected as is customary. The window is now ready for use. As the'window is opened, the uppermost panel il 'will be shifted away from `the weatherstripping I9 land the -lowermost panel il will be shifted 'away from the weatherstripping 22 as supported in the groove 2l. As 4the end clips are rocked lupon their pivotal points l2, their flat pivotal channel faces Ia will rub over the exposed surface o'f the body portion 2G of the weatherstripping 22 as supported within the grooves '28. The rocking of the end clips ill tends to roll the body portion '2'4 laterally. l-lowever,

the flared portion of the groove permits of vthis vrolling `or deforming motion kwithout injury to the weatherstripping, since the groovehas been formed relatively wide enough to permit of Va maximum Yrolling action without Vthe possibility of the body portion coming into contact with any sharp or abrupt corners. The deforming of the weatherstripping is identical in both the opening and closing of the window. The mounting of the end clips upon the jambs, partially compresses the body portion 24 of the weatherstrips and assures of a constant weathering engage- .ment with the .vf-ull surface of each 'of the end clips. Thus the window is effectively sealed throughout its periphery with respect to the several end clips, the upper and lower weathering -of the lupper Vand owermost panels and with the panels being in overlapping weathering contact throughout their length. The weatherstripping imparts a very desirable cushion mounting for the several :end ycl-ipsfand greatly facilitates the operation ,of the window.

It will be apparent therefore that a very novel and effective weatherstripping has beenprovided for the conventional jalousietype windows. The formation of the several grooves -is performed `in asimple manner as the 'frame `members are -extruded and the-several weather strips are inserted intheir 'respective grooves with a minimum of effort. y'The weatherstripping readily conforms to anyirregularity of the window and is most efficient for thepurposes designed.

.it `is to be understood that the invention is not limited to lthe precise arrangement shown, but that changes in the shape, size, materials, and method of assembly are contemplated as readily fall within the spirit of the invention yor the scope of the subjoined claims.
